Conveyor speed
Gear ratio of gearhead

reduction ratio = Feed rate per motor revolution = Pulley diameter [m] × π
When the calculated conveyor speed reduction ratio is used, the conveyor transfer
speed is converted as follows.
Conveyor transfer speed
Rotation speed of motor output shaft [r/min]
=
[m/min]
Conveyor speed reduction ratio
Example:
The pulley diameter is 0.1 m and gear ratio (speed reduction ratio) of the gear head is 20

=
Pulley diameter [m] × π

0.1 [m] × π
䍦63.7
From the conversion formula, the conveyor speed reduction ratio is calculated as 63.7 in this example. This means
that the "speed reduction ratio" parameter (ID: 2085) is 637, while the "speed reduction ratio digit setting" parameter
(ID: 2086) is 1.
When the speed reduction ratio is 63.7 and the motor rotation speed is 1300 r/min, the conveyor transfer speed is
converted as follows:
Conveyor transfer speed [m/min] =

Parameter
•• Position loop gain, speed loop gain, speed loop integral time constant
Vibration that occurs while the motor is accelerating/decelerating or at standstill can be adjusted to an optimal value.
(The optimal value varies depending on the equipment or operating conditions.)
Related parameters
Position loop gain
Adjusts the motor response in reaction to the position deviation. When this value is
increased, the deviation between the command position and actual position will be small. An
excessively high value may increase the motor overshooting or cause the motor to vibrate.
Speed loop gain
Adjusts the motor response in reaction to the speed deviation. When this value is increased,
the deviation between the command speed and actual speed will be small. An excessively
high value may increase the motor overshooting or cause the motor to vibrate.
Speed loop integral Decreases the deviation that cannot be adjusted with the speed loop gain. An excessively
time constant
long value may slow the motor response. Too short value may cause the motor to vibrate.
•• Speed filter
When setting the "speed filter" parameter (ID: 293) while the "speed filter selection" parameter (ID: 2064) is set to
"1: speed filter," the command position is filtered and the motor response can be adjusted.
When the speed filter level is increased, the motor operation at starting/stopping will become smooth. Note, however,
that an excessively long filter level will result in lower synchronization against the commands. Set an appropriate
value according to the specific load and application.

When setting the "moving average time" parameter (ID: 294) while the "speed filter selection" parameter (ID:
2064) is set to "2: moving average," the motor response can be adjusted. The positioning time can be shortened by
suppressing the residual vibration for positioning operation.
